“I have to say that I felt George’s group of six films had more innovative visual imagination, and this film was more of a retrenchment to things you had seen before and characters you had seen before, and it took a few baby steps forward with new characters.” - James Cameron about Episode VII.

Here’s a question I’d like to throw at you, Hal. Let’s just say that Anakin makes an appearance as a Force spirit in The Rise of Skywalker, with Hayden Christensen reprising the role. Even though it may or may not happen, if it were to happen, would you keep the Special Edition change made to the end of Return of the Jedi, or would you restore Sebastian Shaw like everyone else? I still prefer the older Anakin, but I’m curious what you would do with your edit of Return of the Jedi if it does happen in Episode IX.

In that case, I think that we’d just have to accept that this is how Anakin is portrayed now and move on.

It’s hard to imagine a need to include Hayden in ROTJ, barring IX explicitly stating, “Every Force ghost has exactly one appearance and this is Anakin’s.”
I’d like to see a Force ghost appear two ways in IX, such as Luke appearing old and young either close together or to two different people.
